Not to mention Ginny is really damn annoying.
I agree 6th is worst in the series. I wasn't sure about the 5th one, because Harry was extremely emo, but it was supposed to be because of Voldemort infiltrating his mind or something.
7th one was very good and enjoyable, though I kinda missed the spirit of being at Hogwarts.
1 - 4 will always be the best for me.
I like the style the director has taken with the 5th and sixth movies, though. Impossible to follow them if you don't know the story beforehand, but who goes to watch these movies that doesn't?
